/proc/partitions does not have any counts for software RAID, so you can't 
monitor the RAID itself.  It does have counts for the block devices that 
comprise a software RAID so it would not be THAT difficult to write an iostat 
type program that can read /proc/mdstat to determine which devices comprise a 
software RAID and then monitors their stats in /proc/partitions and uses some 
addition to determine the total for the software RAID device.

The CPU overhead of incrementing counters is negligible, there's no reason why 
the counts for software RAID could not be displayed in /proc/partitions, I 
think that this is a minor bug in the software RAID code.

If someone posts a patch to fix it to the linux-kernel list then it should 
have some chance of being accepted.

sane trouble-ticket systems

2003-07-09 Thread Noah L. Meyerhans
Hi all.  I'm searching for a trouble-ticket system that doesn't suck.
Currently we're using RT, and IMHO it sucks.

What I want is something *quiet*.  What I want doesn't break threaded
mail reading the way RT does.  What I want leaves the headers of a
message intact, rather than sending a whole new message, with the
original headers pulled out and stuck in the body.

I've talked to a coworker about this, and what we decided would be
*really* nice is a trouble ticket system that works on the same
principle as mutt's mail threading features.  That way, the TT system
can be completely transparent, especially to the end-user (i.e. no need
to put a ticket number in the mail subject).  Even in cases where the
end-user's MUA doesn't support the In-Reply-To header, mutt can still
make intelligent decisions based on the message subject.  I think a good
TT system could work in a similar way.  Does such a system exist?

What other TT systems are worth investigating?  It doesn't need to be as
heavy as RT, which I think is overkill for our 10 person service
organization with roughly 800 users.  (Though I think the service
organization will be growing, I still think RT is heavier than it needs
to be.)

Thanks.

Ah yes, that's right I remember now.  This is exactly the kind of situation
as to why you shouldn't use CNAME's for MX names or for any official machine
name for that matter.  CNAME's are just for human convenience, a host should
never try to pass itself off by one.  Screws up the double reverse lookup.

But what ur saying is that there simply is no PTR record for the IP at all.

Re: Anyone willing to relay for me for a price?

2003-07-09 Thread Rod Rodolico
In Dallas (TX, US), SBC provides DSL with the option of Business Class
DSL, providing 5 static IP's. I believe that on the west coast, PacBell
provides standard class DSL with one static IP (they did a year ago).
Business Class DSL costs $75/mo, while the PacBell thing was around $40/mo
if I remember correctly.

Again, in Dallas, I could go to another ISP who buys DSL form SBC and
resells it. Some, I've heard, would provide me with one static for a very
low cost.

Check again for DSL providers in your area, especially resellers.
Resellers generally buy large blocks of IP's and some of them give you
statics as part of the package, others at an additional cost. I hosted a
half dozen sites on my DSL line for a few years after it became available,
then eventually moved it to a colo. However, my secondary DNS is still
sitting on the same DSL.

Yes, that is moderately useful, which is more than I can say for the
information provided by BT, my ISP.

I'll check.

I'm particularly angry as I pay less than $800 per month but way more
than I need to so I get "business" broadband ... to no advantage I can
see!

Again, I have that problem but I haven't seen many or any bounces that
I think are down to that.  Another thing I have to get onto the ISP
about again.  This is mad.  I'm all in favour of clamping down on spam
but this is cutting the Internet down to a very two class system as
you say.

If I remember right, you should never make an MX record direct to a 
CNAME, for reasons that I can't remember right now.

All the same, you are right, I could just make my MX be the PTR and most 
MTAs would be happy.

Unfortunately, the record does not exist, so no help there.

But does a PTR record exist?  The double reverse lookup should succeed so
long as there is a valid A <-> PTR pair.  Regardless of whether it was
launched into from another A or CNAME or IP.  Unless I'm way off base here,
it goes presented name -> IP lookup -> PTR lookup -> IP lookup.  If the two
IP lookups match, the test is passed.
